Dreams of a baseball pitcher represents initiation, getting the play or interaction started. Perhaps this dream is giving you the message to get the game started or to be more focused. Perhaps you playing hardball in your negotiations or business dealings, asking tough questions, and being confrontational and/or combative.
If you are throwing a curve ball, then you are being tricky, manipulative and trying to throw others off balance so that they strike out.
If you lob the ball, then you are attempting to make it easy, even abdicating your power to the player up at bat.
If you are up to bat, dealing with the pitcher, then you are feeling on the defensive. See Baseball.
